Abstract
We have measured branching ratios for three LAMBDA(c) decay modes that have a SIGMA+ in the final state. Two of the observed decay modes, LA MBDA(c) --> SIGMA+pi0 and LAMBDA(c)+ --> SIGMA+omega, have no external W-emission amplitudes. Their branching ratios relative to the pK-pimode are 0.20 +/- 0.03 +/- 0.03 and 0.54 +/- 0.13 +/- 0.06, respective ly. We have also significantly improved the measurement of the branchi ng ratio for the previously observed decay mode LAMBDA(c)+ --> SIGMA+p i+pi-. We find its branching ratio relative to pK-pi+ to be 0.74 +/- 0 .07 +/- 0.09.
